Where is Slugger 3GL suited?
Slugger 3GL can be used for establishment, renovation and overseeding across a range of managed turf applications, including sports turf, golf tees, fairways and roughs. It is also suitable for overseeding dormant warm-season turf.
Establishment and overseeding
Slugger 3GL can be used for new establishment or for renovation and overseeding of existing turf. For best results, establish into prepared bare soil or after verticutting to improve seed-to-soil contact.
- New establishment: 25–35 g/m²
- Renovation and reseeding: 15–25 g/m²
- Overseeding dormant warm-season turf: 35–50 g/m²
Good seed-to-soil contact and adequate moisture during establishment will help support successful germination and turf development.
Mowing height
Slugger 3GL is recommended for turf maintained at mowing heights of 12 mm and above.
